And we didn't discuss zIIP-eligibility... ... It's a bit like compiling REXX...
... Don't expect it to buy you much if the things being scripted are heavy compared to the things scripting them. Effectively the command processors are JNI.

Then someone else said we don't really need that, because NetREXX fulfills the desire to have REXX code that can be JITted. But then someone else pointed out that NetREXX can't do all the same kinds of things that REXX can, especially with respect to TSO and ISPF integration. > > Therefore, as NetREXX can't substitute for REXX, we still have the desire (if, perhaps, not the need) for a true classic REXX that can make use of the JIT technology. Best post in this thread! We want a JIT for classic REXX so it can run at speeds similar to compiled languages. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
